SixBit Software was introduced in Feb. 2009, but our roots go far deeper than that. You may know us as the team that created “AuctionAssistant” (1997), “Seller’s Assistant” (2001) and “Blackthorne” (2005). For years, we have been developing desktop auction management software for eBay sellers and we're now happy to offer you our biggest and best eCommerce tool to date. We hope you join us and track our progress as we continue to grow.

Our Mission Statement

At SixBit Software, it is our mission to provide, low-cost, fully featured eCommerce management software to make entrepreneurial individuals and small companies more successful selling on the internet.

Our Beliefs

We believe the marketplace is more vibrant, and better served with a large number of smaller sellers, rather than just a small number of corporate sellers. We believe that actions speak louder than words, and encourage you to monitor our progress. We believe in always telling our customers the truth, even when it isn't what they want to hear. We believe that users of our software are partners. We believe that it is absolutely imperative to have users involved with the design and testing of our applications throughout their entire life cycle. We believe that every internet seller is different and requires different features, support and pricing options. We believe that a selling solution should grow with its users. It should be easy enough to allow new sellers to list their first item, and be capable of handling hundreds of thousands of sales.
